The Rabobank sprinter came into the stage as an outside bet for the win and heading into the final 10 kilometres he was in contention to take his first Tour de France stage but inside the final kilometre, with a bunch sprinters jostling for position, Renshaw became isolated and was unable to pull himself back into contention.
"I didn't even get a chance to sprint," he told Cyclingnews after crossing the line.
"I couldn't get out and I was boxed in on the barrier and didn't get to even sprint. It's disappointing."
Like all but a couple of his rivals Renshaw lacks a complete leadout train in this year's Tour and in the Australian's case he was left with Maarten Tjallingii for help in the closing stages.
"My legs got better throughout the stage but it's disappointing not to have a better sprint. I had Maarten Tjallingii leading me out and he did a great job actually. Now that I know how strong he is I can maybe save him for a bit longer."
"Without a HTC style leadout the speed isn't so high and there was a lot of jostling and it just means it's harder to judge the sprint."
